GCS 2012 Impulse Generator Digit Control System

1) The PLC technology control system can supply many kinds of control to the generator and meet the requirement of impulse test. The control system is consist of control cabinet(include auxiliary operation unit) and main operation unit, two parts. Control cabinet is set at the bottom of generator and beside of DC charging apparatus. Main operation units is set inside of control room,two units is connected with two core optical cable.

2) Control cabinet core device is FXZN programmable controller, and controllable silicon control circuit,trigger pulse generate and time-delay circuit, isolation protection circuit board.
3) Main control unit and auxiliary operation unit are adopting schematize man-machine touch screen as input/output control component, operation units is small and exquisite,appearance as 19 inch 7U standard crate, all orders are finished by touch screen. Operation unit is connected with computer by RS232 connector, which use special control software package and also can be automatic observed and controlled by computer.

Main Function: :
GCS2000A controller can realize manual control, automatic control and programmed control,
main function are like following:
Measuring display:
1) DC charging voltage
2) Transformer primary current
3) Generator sphere gap distance

State Display: 
1) Main power connector switching state
2) Ground device switching state
3) Generator sphere gaps trigger state
4) Generator charging voltage polarity state

Control: :
1) Control system can realize manual control, automatic control and programmed control,each function is independent.
2) Adopt controllable silicon regulating method, has charging voltage feedback measuring system
3) Sparking sphere gap and chopped gap distance is adjustable manually or automatically,and display on the interface.
4) Equips time-delay adjustable chopping gap trigger pulse, and generator spark trigger feedback system
5) Adopt functions controlled constant current charging methods, charging voltage stability can reach 0.5%.
6) Liquid crystal display panel can indicate generator’s charging voltage and charging process, accuracy is 1%.
7) Can direct input charging voltage and time from liquid crystal display panel
8) Equips charging abnormal protection function, the trigger spark pulse can be generate manually or automatically
9) Generator working status indication, such as: spontaneous combustion, not trigger, charging abnormal,charging stable, and so on.
10) System generator and charging parts ground and ground decontrol
11) The charging voltage polarity can be changed by press the button in the controller.
12) The charging process can be controlled manually or automatically
13) Alarm bell (manual or automatic)
14) Protection and interlock:
15) Over-current protection
16) Over-voltage protection
17) Abnormal discharge protection
18) Door open/close interlock
19) Ground facility interlock
20) Polarity reversal interlock
21) Operation indication:
22) Can supply different operation indication, when system error or disoperation, the interface will come up relative indication.
